ARM: dts: vf-colibri-aster: Add support for Aster with Vybrid

Add support for Aster carrier board with Vybrid.

Notes:
- In case where the RPi standard specifies a GPIO and we have another
pinmux for the concerned pin due to Colibri standard, the Colibri
standard has been given preference.

- Vybrid DSPI driver does not support the use of GPIOs as chip selects.
On Aster Colibri standard SPI chip select is exposed on Arduino header
and a GPIO for chip select is brought out on RPi header. Since DSPI
driver does not support use of GPIOs as chip selects and to allow use
of DSPI on both Arduino and RPi headers, the chip selects have been
multiplexed as GPIOs.

The user space application will be responsible for controlling these
chip selects explicitly.
